Just to add to this: If your child has a favorite blanket or toy, prepare them for having to put it through the scanner with the carry ons. The time I took my GD on her first , she had a favorite stuffed green bunny rabbit that she couldn't sleep without. We had packed bunny in her carry on and I'd warned her the bag had to go through the scanner, while we had to walk through another scanner. However, apparently she didn't understand as well as I thought she did. Just as her carry on started to go through, she started screaming, "They're killing bunny, they're killing bunny" and tried to jump on the belt to follow her carry on through. Thankfully everyone else seemed to think it was hilarious. I was ready to strangle her.

Once we got her though the scanner and grabbed our carry ons, she insisted on opening the carry on to make sure bunny was safe. She grabbed him, saying, "Oh I thought they'd killed you, I thought I'd lost you".

Funny now, but not at the time.
